Time Warner Cable is the latest company exploring a possible investment in online video joint venture Hulu, The Wall Street Journal reported on May 15.

It wasn't immediately clear if the company would look to buy a stake or make a full acquisition, according to the report.

Bloomberg News reported that the second-largest U.S. cable operator would join Walt Disney, News Corp. and Comcast/NBCUniversal as a co-owner of Hulu. NBCUniversal has a passive stake in the online video firm as regulators prescribed when Comcast acquired the entertainment company.

The Journal said that a second, unidentified pay-TV operator is also considering a Hulu bid.

Among other companies known or believed to be considering a bid for all or part of Hulu are former News Corp. COO Peter Chernin's Chernin Group, Yahoo, Amazon.com and financial services firm Guggenheim Partners, whose Guggenheim Digital Media arm owns The Hollywood Reporter.
